Winterization - Columbia Coronado 25 Owenrs Manual

cutting, and drilling, work is done on the hull or deck, take care to watch your
tools for dulling. Drills and taps, for example, dull quickly and should be
sharpened or replaced when inspection shows wear. National Coarse Threads are
generally preferred to National Fine Threads, i.e. 10/24 NOT 10/32.
Saw cuts can be made with special sabre saw blades (see Suppliers and Vendors
List) or with an abrasive wheel on a high-speed drill motor.
Any rough or uneven surfaces may be ground or sanded with a disk, belt, or orbital
sander. Avoid breathing the dust as it is an irritant to the respiratory system.
It is suggested that a mask be worn over the mouth and nose so as not to inhale
powdered fiberglass.
Likewise, power tools should be blown free of fiberglass dust, since it is
an abrasive in bearings, motors, and gears.
NOTE: Caution should be used at all times when working with power tools
on fiberglass. The fiberglass is a very hard material and tools
have a habit of slipping, sliding, and jumping out of place.

Winterization

For all boats with inboard engines and heads that are shipped to areas that have
below-freezing temperatures, it is strongly recommended that the engine cooling
system be winterized by utilizing an approved anti-freeze. The approved
anti-freezes for the Perkins, Westerbeke, Palmer, and Atomic 4 engines are as
follows:
DOWGUARD
HUBBARD - HALL
PEAK
PERMA-STA
PERMAGUARD
It is also strongly recommended that the water tanks and the head be
completely drained of water, including all the lines.
